Caller Applications Caller Applications are a collection of menus and prompts that enable
administrators to extend those parts of the Modular Messaging telephone
user interface (TUI) that are accessible to callers.
Using Caller Applications, administrators can extend the system
Automated Attendant and the Common Caller Interface (CCI), depending
on the requirements of the organization.
Some basic functions that a Caller Application can provide are
transferring callers to a specified mailbox, allowing callers to record
messages, sending messages to either a mailbox number or an e-mail
address that is configured as part of the Caller Application, and providing
directory assistance for callers to use the dial-by-name functionality of the
TUI.
Caller applications can perform additional functions, such as:
! Automating call handling and routing incoming calls directly to
departments within the organization
! Creating daily ‘bulletin board’ announcements for callers and
subscribers
! Allowing for greater flexibility and more options with respect to
system and personal greetings
Note: Caller Applications are created using the Caller Applications
Editor. For more information, see Caller Applications Editor
on page 3-4.
Difference between a Caller App and an Aria Mailbox Type
The Octel 250/350 series of voicemail systems allows extensive
customization of the telephone user interface through the use of Enhanced
Call Processing (ECP) mailboxes and other types of mailboxes.
A Caller Application is not a mailbox. Specifically, it does not require that
a mailbox be created on the message store, or be dedicated to its use. A
Caller Application contains one or more nodes, each of which can interact
with the caller, and pass control to another node. The actions which a
particular node performs will correspond, in many cases, to actions
performed by a certain Aria mailbox type.
Not all Aria mailbox types are emulated by Caller Applications. A Caller
Application is best thought of as a single-digit menu or as nested
automated attendants, comprising a collection of actions of the various
types supported, that is:
! Menu (simple, or with extension, mailbox or caller app)
! Transfer (operator, extension or mailbox)
